ABSTRACT:
When a function change key on a keyboard is operated, a key check section detects its operation and sends a function change key code to a function-key-use right changing unit. In response to this code, the unit calculates the window number of a window different from the window currently having the function-key-use right, and notifies a function key notifier that the calculated window is a new window having the function-key-use right. The same unit directs a CRT controller to display a marking frame around the function area of the new window. Upon depression of a function key, the key check section inputs a function key code to the function key identifier. The function key identifier notifies the task operating in the window having the function-key-use right of the input function code.
